When Clayton Kershaw went on the disabled list early this month, Dodgers manager Dave Roberts said the rest of the staff must pick up the slack, and Kenta Maeda has stepped it up. Coming off eight scoreless innings in Miami, Maeda added 6 2/3 more while striking out 12 and allowing only two hits Wednesday night as the Dodgers blanked the Rockies, 3-0, at Dodger Stadium. After taking the rubber game of the series, the Dodgers are 3 1/2 games behind the first-place Rockies.
